The 1998 Gaming Table has one Red Rock Inn listed as opening in 1989 with an address of 5350 W. Charleston not 5640 W. Charleston as you see on this cover. I would guess this cover is from the the early to mid 60's as it has no area code yet. You can look up the address on the google maps with the street view option, big fun, looks like a run down strip mall parking lot now! Enjoy, Eric
